The air deflector should work regardless of the A/C condition, so you should be able to select front vents, defrost, or floor. The A/C light still should come on when low on freon (ask me how I know), but the compressor will not kick on. If the relay is bad, the A/C lights won't come on (to the best of my knowledge).
